Application filed September 22, 1919. Serial No. 325,570.

T 0 all whom it 'ni-ag conoerw Be it known that I, LLoYn F. SCI-IRADER,

"a citizen of the United States,and reside New York, N. Y.,' have mvented cering in tain newfand useful Improvements iIl'RG- versing Mechanism for By-Product Coke Ovens, of which the following is a' specification. f

My invention provides certain improvements in reversing mechanisms for coke ovens in the direction of economy of construction and ease of operation and maintenance.

The accompanying drawings illustrate an embodiment of the invention. 1

Fig. 1 is a side elevation of the lower part of a coke oven to which the invention; is

applied, the central portion being cut-out;

.Fig. 2 and Fig. 3 thereof; i

Fig. 4 is a .plan of the same; I Fig. 5 is an end elevation of the same. Fig. 6 is an enlarged detail thereof. Referring to the embodiment of the inare enlarged details vention illustrated, the oven as a whole is.

designated by the numeral 2. Along, the sides thereof there is arranged a number of gas valves 3, one for each coklng chamber and. a corresponding number of air valves 4. The gas valves for example maybe ofthe type shown in Fig. 2. Gas isadmitted from a main 5 and passes through pipes .6

The operatlng strike the arm 8 A variety of valves and valve mechanism are? been I I thus heated in the previou' s l stag'ei are now receiving 'freshair and to cut itlofi 4 fromthose through which-the burnt gases invention provides for single I crating motor connected both to thejg'a and-;

Thefports' of"the I, gas and air valves and the throw ofl th e j controlling parts thereof may bearranged as desired to cutoff the gas slightly before an electric motor19, Fig tn mounted at one I within a casing 20. The driven shaft. 21 has on its opposite projecting ends arms 22 and'23.-at the ends ofwhich are. pivoted links 24 and 25 connected to cables 26 and 19 respectively of the valves. v The cables 26 extend over guide pulleys 28 and 29 to the forward ends of-the' operat-.-

.85 1 mg rods 18 for the air valves on opposite T9771 sides of the oven. At the rear. ends of these rods they are connected toeach otherby a cable 30 which runs over guide pulleys 31 atjthe rear and is provided with" a turn buckle to take up the slack. Theca-bles 27- extend over pulley-s 32 and. 33 to the forward ends of the gasvalve operating rods and the i latter are connected'togetherat their rear ends by. a cable 3 1- which extends aroundpulleys 35 and is provided with a turn buckle'36,- Fig. 4. Turn buckles3' 7 and 38,

are provided also infthe cables 26 "and 27 I i for taking up the slack.

and 23 throw the cables and valve: "operat ing. rods for the gas valve in..*one'direc- I tion and for the airvalves inthe opposite tions, Figs. 2 and 3, and are reversed at operated about once every half hour to Though I, have described withgreat Il -10 my inventioiniyet it is not to be understood therefrom that the invention is restricted to the particular embodiment disclosed. Various modifications thereof in detail and in the arrangement of the, parts may be made by those skilled in the art Without departure from the invention as defined in the following claims.

What I claim is:

1. Mechanism for operating the air and gas valves of a coke oven, said mechanism iiicludingin combination actuating devices forf'said valves and a common motor for revers ng at the same time the actuatingdevices for both sets of valves. v

2. Mechanism for operating the air and gas valves of aicoke oven, said mechanism including in combination reciprocable rods for reversing said valves and a common motor for reciprocating said rods at the same time.

'3. Mechanism for operating theair and gas va ves of a coke oven, said mechanism including in combination reciprocable rods them at the same time. 7

4C. Mechanism for operating the air and gas valves of a coke oven, said mechanism including in combination reciprocable rods for IGVBISlIlg said valves and a reversing device adapted to be actuated at suitable intervals, said rods being connected directly to said reversing device sofas to be moved simultaneously When the reversing device is actuated.

In W1tI1eSS whereof I have hereunto signed my name.
